Abstract
Disclosed is a centrifugal liquid pump, preferably of the rotary disc type, which incorporates a gas injection assembly of very simple yet efficient structure, whereby up to 15% per volume of a gas such as air, may be mixed with the pumped liquid. The gas injection is achieved with a gas feed pipe that enters the pump through its axial inlet and with a plurality of gas injector pipes that projects from the gas feed pipe radially within the impeller.
